Which fit'sf'within .the upperendzof'the cylinderb..y Th'epackmgfrings are of similar construction, eachbeing' provided .with an annulus dlfjof' pa.cking`mater3ly ring d8l is Y shown in Figs. Lfj'and '6. Each ring has con- Ilected with its end portions links d, joined to eccentrics d, carried by shafts (Z13, one of which projects upwardly from the ortion c of the member C and the other of w ich projects downwardly from the portion c of said member. The shafts are accessible from the exterior, as shown in Fig. .1, and have square ends for receiving a wrench. lt is obvious that the packing-rings may be collapsed readily by the means described when it is de- 'sired to separate the filter-sections, andit is likewise obvious that they may be expanded to produce tight joints when the filter-sec tions are assembled. It is convenient to confine the packingrings by means of plates d14 dw, as shown in Fig. 5, `the passages d5 @Z7 eX- tending through the plate d, as shown. The cylinder d is equipped with rings d1? d, havinfr pivotal portions dis d, respectively, jour naied on the standard A', and having hooks d2", 'engaging the standard A2. The pivotal portion (119 is equip ed with a downwardlyextending sleeve di; having threaded engagement with a sleeve (Z22, formed integrally with a pinion d, journaled on the standard A and actuated by a pinion 124, secured on a shaft 25, journaled in a bracket e126, carried by the standardAC By this means the filter D may be independently' elevated.

The top E for the cylinder d may be raised through. the medium of its screw, which is equipped with actuating means E3 of wellknown construction. When the top E is elevated, the cross-beani E2 may be swung on its pivot e in the usual manner.

When it is desired to use the filter as a compound filter, an inlet-hose f is connected with the inlet c11 of the upper filter, a hose is employed to connect the outlet c12 of t e upper filter with the inlet a of the lower filter, and a diseharge-hosef2 is connected with the outlet-discharge a of the lower filter. Vith this arrangement it is obvious liquid will enter the annular chamber of the up er lter, pass through the cells of the upper lter, find an outlet through the central conduit of the upper cells to the pipe cl2, thence pass through the hosef, enter the annular chamber of the lower filter, thence pass through the cells of the lower filter, and emerge through the central conduit of the lower filter to the hose f 2.

' V`When it is desired to use the upper and lower filters as independent filters, the hose f may be disconnected from the ipe a and moved to the position indicated y dotted lines to serve as a discharge-outlet from the upper filter, and a hose f3 may be connected with the inlet-pipe a of the lower filter and serve as an. ingress for the liquid to the lower filter. When thus arranged, it is obvious that each filter may be operated `independently of the other. When the device is used as a comound filter, it is obvious that the liquid will have to pass through more cells than where the filters are used independently, so that it is possible to suit the filter to the conditions of the liquor being treated and according to the results desired. It is obvious that when the lter-sections are in alinement and properly assembled pressure may be transmitted. from the press-screw E through the cells of the u per filter and the intermediate member C to t e 'cells of the lower filter. The arrangement is designedly such that the filter-sections will swing in alternation in opposite direction s-that is, in alternation about the standards A A2 as pivots-thereby balancing the filter when the sections are swung to opposite positions.

It is to be understood that I have de scribed my invention in detail for clearness of understanding only and without intention of unnecessarily limiting the invention.

What I regard as new, and desire to secure by Letters Patent, is-

1. The combination of a group of alined filter-cells, an inclosing cylinder, a second group of alined filter-cells in alinement with the first group, an inclosing cylinder for the second group, means for transmitting pressure from one group of cells to the other group of cells, and independent inlet and outlet passages for the alined filters thus formed, for the purpose set forth.
